A passenger car with front and rear fog lights travels in heavy snow with particularly poor visibility. What must the driver do regarding fog lights?

Correct answer

Switch on the rear fog light; front fog lights are optional in this situation.

Switch on the rear fog light; front fog lights may be used but are not themselves compulsory. Use the other required lighting: Article 106 allows front fog lights or dipped or main beam, subject to non-dazzling rules and required position lights. Keep rear fog lights on only while conditions are particularly adverse; switch them off when those conditions cease.
